In a stadium an athlete is running on a circular path with uniform speed during a practice session. The angle covered by him during one second is found to be `10^@` by a coach observing him from the centre of the circular track. What would be the measure of angle (in degrees) described by the athlete by an observer standing on the circle?

A
